What is a graphical representation of alternating current?
The symbol for alternating current is: ~
What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
What is alternating current normally produced by?
Alternating current is normally produced by rotating the magnet in the coil of an induced alternating voltage. When connected to a circuit, an alternating current will flow.
Does vac stand for volt amp current or volt alternating current?
It stands for volts alternating current.
What did alternating electrical current effect in the 1920?
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
What opposes the flow of electric current?
Resistance in OMS: In alternating current is is measured in impedance.
How does the voltage across a load is measured in a circuit with alternating current?
It's measured with an AC voltmeter.
What opposes the flow of an electric currents?
Resistance in OMS: In alternating current is is measured in impedance.
What is an opposition to current flow called that occurs in an alternating current circuit?
The resistance is called impedance, and is equal to the measured voltage divided by the measured current, through Ohm's Law (V = ZI, Z = V/I).
What is ac and what is DC?
DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).
What is current that keeps changing direction?
AC, or alternating current.AC, or alternating current.AC, or alternating current.AC, or alternating current.
What is alternating current machine?
"What is alternating current machine?"

An electric current is the measure of what?
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
